This invention relates to an industrial truck adapted to place to place.

One object of the invention is to construct 'a truck ofthis. character capable of readily engaging a body or bodies to be transported from place to place.

Another object of the invention is to construct an improved elevating truck having an adj ustable body engaging and lifting member capable of being readily positioned ,to engage a body without moving the truck.

Another object of the invention is to provide an improved lifting member capable of fitting over or envelopinga portion of the body to be lifted, whereby it may be engaged and moved.

Other objects of the invention will be apparent to those skilled in the art-to which my invention relates from the following description taken in connection with the accompanying drawings, wherein Figure 1 is a side elevation of a truck embodying my invention.

, igure 6 is a section on the line 66 of Fi ure 4.

Figure 7 is a fragmentary view showing a slightly different form of construction embodying my invention.

Figure 8 is a section on the line 8-8 of Figure 7.

n the drawings, 1 indicates a frame suitably supported on wheels,'2, 3, preferably two pairs of wheels-see Figure. 3. The frame 1 may be of any desired construction, but it preferably consists of a pair of parallel channel bars 1 and a supplemental frame 1 forming side sections 4 which ex tend laterally to a point substantially coincident with the plane of the outer extremities of the wheels 2, to provide guards therefor, as well as a relatively w-ide base or platform for a plurality of'batteries 5. The batteries 5 may be housed within a suitable casing 6. 7"indicates a pair of uprights is a section on thei line 5-45 of secured to the bars 1 adjacent one end or transport bodies from looking toward supports for suitable brackets or plates for the controlling devices, to wit, a controller 8 and its operating handle 9 for operating a traction or driving motor 10, a steering lever 11 and a controllerul2 for the hoisting or elevating motor 13. In the drawings, for illustrative purposes, 'one pair of wheels is driven and both pairs of wheels are steerable, but it will be understood that such arrangement may be variously changed at will so that either or both pairs of wheels may be driven and either pair steered.

14 indicates a platform for the operative, while operating the truck, to stand on and to actuate the lever 11, handle 9 and the handle 12 for the controller 12. The platform 14 may be pivoted on a rod supported by a pair of depending brackets 15. The platform 14 may be counterbalanced by a' weight 16 to maintain it in upright position when not in use. 17 indicates a brake for the truck, preferably operatively connected with an element driven by the motor 10. The brake 17 is controlled by a pedal 17 associated with the platform 14.,

18 indicates a guide frame for an elevat-' ing member 19, preferably arranged at that end of the frame 1 opposite to the platform 14 and the truck controlling devices,

The guide frame section 18 preferably comprises a pair of channel or I-beams 18 rigidly maintained in spaced, parallel relation by a cross member20 arranged intermediate their ends, a sill 21 disposed at the upper ends of the beams 18 and connections with the main frame 1 of the construction shown in the drawings, the, side walls or flanges of the beams 18 serve as guides for shoes 23, which are supported between the beams 18 and form a part of the elevating member 19. 24 indicates a pair of tie rods or bars extending between and connected at their opposite ends to the upper ends of the beams 18*, or angle plates 24' secured thereto, and the frame 1 and serving to brace the guide frame 18 against movement relative to the. main frame 1, due to the weightof the load which at any time may he supported on the engaging and lifting member or device 25, to be later referredto. The sill 21 preferably comprises a pair of channel bars 21, 21, supported upon and secured to the angle plates 24, each of which is secured to the outer side of one of the I- beams 18, in a well known manner. The sill 21 serves to support certain elements of a hoisting or elevating mechanism 26, to which reference will later be made.

The elevating member 19 comprises a pair of shoes 23, already referred to, connected together by a pair of spaced front and rear plates 28 and upper and lower pairs of shoe devices 23', one device of each pairbeing carried by one of the shoes 23 and engaging the inner opposing side walls of the adjacent beam 18. Each shoe device 23 consists of a roller loosely mounted on a stud shaft 29 supported in the wall of the adjacent shoe 23. The shafts 29 are inclined so that the surfaces of the rollers may engage the'inclined inner surfaces of the side walls of the adjacent beam 18 and roll thereon with minimum friction. As will be understood from Figures 2 and 3, the stud shafts 29 carried by each shoe 23 are inclined at an angle relative to each other and are offset relative to the central longitudinal plane of the adjacent beam 18?, so that the lower roller will engage the rear side wall-of the beam and the upper roller will engage its front side wall.

The device 25 is arranged to engage a body or bodies to be transported or loaded and unloaded to or from a support or pile or engaged, elevated and transported to some station and lowered.

In the form of construction herein shown, the device 25 is of hollow form, enabling it. to fit over or envelope one end or an exposed ortion of the body to be liftedor moved. he wall of the device maybe constructed to form an opening 25' of any desired shape according to the construction or shape of the body to be engaged, but when trh-body to be engaged, lifted and transported consists of a roll such as used in a rolling mill,

the opening is round, as shown in the draw-- ings, so as to receive one end of the roll when the truck is driven toward it as will later beset forth.

The device 25 is carried by a supporting element 30.,which in turn is trunnioned onv element 30 is provided at its opposite sides with trunnions 32, which rotatably fit suitable openings 33 formed in a pair of forwardly projecting arms-34, each integrally connected to one of the shoes 23. By preferance, the trunnions constitute a single rod extendingthrough openin s formed in the supporting element 30. The trunnions 32 serve to removably support the lifting device on the elevating member 19 and also permit it to swing outwardly and upwardly, so that during the lowering movement of the load, if anything happens to be below the latter, it may swing upwardly about the trunnions and thus eliminate danger of breakage or distortion of any part of the elevating member, lifting device or other parts of the truck. As clearly shown in Figure 5, the supporting element 30 extends inwardly beyond the axis of the trunnions 32, so that its inner end may engage the lower edge .body to be lifted, the elevating member is raised or lowered to position the lifting device at the same height as the body; then the truck is driven toward the body to be lifted and in close proximity thereto. If it is found that the lifting device is not positioned to receive the body, it is adjusted, that is, rotated in the supporting member 30, and the elevating member adjusted up or down, until the opening 25 is in registry I with the body; then the'truck is driven forwardly thereby causing the liftingv device tolenvelope or fit over the body end or an exposed portion thereof, whereupon the elevating member is raised and the truck backed and driven to the desired location.

From the foregoing description it will be seen that the lifting device may be adjusted in a ready manner into alignment with the body to be engaged and lifted without moving the truck. The construction not onl facilitates the operations, but

enables the lifting device to engage and lift bodies the exposed portions of which are relatively short and small.

The rotation or adjustment of the lifting device 25 may be effected by inserting a tool in one of the openings 25 formed in that portion of its wall extending beyond the supporting member 30.

-At 25*, the outer wall of the lifting device 25 is formed with an annular groove which forms a key-way for'a bolt 25 extending through a transverse Opening formed in the supportlng element 30. This construe- I tion serves to removably maintain the lifting device 25 in the supporting element 30,

while permitting it to be rotated in the- ,13, already referred to, and winding drums 42 driven thereby. The motor and drums are mounted on standards 43 which are fixed upon the main frame 1, preferably between the battery casing 6 and the guide frame 18. The drums 42 have connected to them flexible members '44, ,44, such as cableswhich are operatively connected to the ele-- vating member 19, as will be later described. The elements constituting the operating means herein shown and just referred to are similar in construction to and co-operative like corresponding elements in m copending application Serial No. 592,138, filed October 3, 1922, Patent No. 1,567,676, dated December 29, 1925, to which referencemay bemade, except that, as will be noted in Fig. 1, the standards 43 for the motor supporting cradle are arranged to support the latter and the motor 13 in substantially a horizontal position.

45 indicates hangers mounted on and secured to the channel bars 21, constituting "the sill 21. The hangers are provided with suitable bearings 47 which support the oppositeends of a shaft 48. 49, 49, and 50, 50, indicate pairs of sheaves loosely mounted on theshaft 48 and preferably arranged equal distances from a point midway between the guide members 18. '51, 51, mdicate a pair of sheaves loosely mounted on a shaft 51 supported at its opposite ends in the channel bars 21 and arranged at right angles to the shaft 48 w1th its axis in a plane preferably midway between the drums 42. 52, 52, and 53, 53,

lndicate pairs of sheaves loosely mounted on shafts 54, 55, respectively, disposed at opposite sides of and equal distances from the plane in which the shaft 51 is supported and supported at their opposite ends in the plates 28. The ropes, cables or flexible members 44, 44, run over and around the sheaves and are adapted to be wound on and from the drums 42, ,to raise and lower the elevating member 19, together with whatever load is to be carried or transported or moved vertically by the lifting.

device carried thereby. The rope 44 extends from one drum 42 over the sheave 49, then around the sheave 52 and then over the sheave '51.. From the she'ave 5l, the rope 44 runs around the sheave 53 and then around the sheave 50, its free end being connected to one end of an equalizingelement 56, which is pivotedon a pivot 57, preferably disposed in the plane of the shaft 51, and supported by the cross bar 20. The other rope 44' extends from the adjacent drum 42 over the sheave 50, then around. the sheave 53' and then over the sheave 51. From the sheave 51' the rope 44 runs around the sheave 52 and then over around the sheave 49, its free end being connected to the opposite end of the equalizing element 56. The operation of winding the ropes 44, 44 on the drums 42 and unwinding them therefrom to raise and lower the elevating member will "be readily understood. Froin the foregoing description, it' will be seen that the ropes 44, 44, are wound on and off drums which are disposed at opposite sides'of the central longitudinal planeof the truck frame, or a point which is midway between the guide mcmhere; also that the rope wound on and ofi one drum is carried over sheaves which are arranged equal distances from this point and connected to the-end of the equalizing ele- 1nent,..which is arranged on that side of the central longitudinal plane of the truck remote from the drum. By-this arrangement the pull on the ropes incident to raising and Y lowering the elevating member and its load is equalized so that the force acts snnultaneously through the sheaves v52 52, and 525,

53', and the shafts therefor, to operate the elevating member vertically and in adirec- 7 tion parallel to the guide members 18 thereby eliminat ng any tendency to pull on or raise or lower one side of the shoe member faster than the other side. As a result,

the elevating member 19 is guided freely between the guides 18 in its vertical move- I (2) wear substantially equally.

In Figs. 7 and, 8 I have shown a modified form of construction in which the lifting device indicated at 25 eomprisesa shaft or shank 58 rotatably fitting a hub 30* on the supporting member 30 which is trunnioned at'i-lll on the elevating member, and a socket 58 having an annular wall 58 that is eccentric to the axis of the shaft or shank 58'.

The inner end of the, shaft or shank 58"is preferably provided with screw threads to take a nut. 59 which engages the adjacent end of the hub 80 to maintain the lifting device on the supporting member, while permitting it to be rotated to effect adjustment of the socket in the manner already set forth in connection with the lifting device 25. 60 indicates an arm on the supporting member 30 and arranged to engage a part of the elevating member, for example, the rear plate 28 thereof, to support the lifting device against downward movement, but permitting it to swing upwardly.

To those skilled in the art to which my invention relates, many modifications and widely differing embodlments of the invenlion and applications thereof will suggest themselves without de arting from the spirit and scopethereof. The descriptions and the disclosure herein are purely illustrative and are not intended to be in any sense limiting.
